Why do you feel sleepy in spring? When the weather gets warm, many people begin to feel sleepy. If you want to relieve spring sleepiness, you need to know the reason first. Why do you feel sleepy in spring? Is there any way to prevent it?
Why is spring sleepy?
As the saying goes: poor in spring and poor in autumn, this is a normal human feeling. Health experts point out that spring sleepiness is a physiological phenomenon of human physiological function with the natural climate change.
Under the influence of climate warming, the skin blood vessels of the human body gradually expand, the blood flow also increases, the blood flow of the whole body is reconfigured, the blood supply and oxygen supply of the brain are relatively reduced, and the brain tissue reduces its excitability for self-protection, so people have sleepiness.
In spring, the warming temperature accelerates the metabolism of the human body, and the oxygen consumption of the whole body increases, which leads to the decrease of the oxygen supply to the brain. In winter, the brain has developed a dependence on the hyperoxia environment, and it can't adapt to the changes of the environment in a short time, so the excitability of the brain is inhibited, and people feel sleepy.
In addition, many families or office buildings turn on air conditioning in a closed environment, resulting in high levels of harmful gases such as carbon dioxide in the air, which will also aggravate the symptoms of spring sleepiness. In the office building, if 20% of the people have symptoms such as drowsiness, yawning, eyes unable to open, face flushed, tears in the wind, hair loss and so on, the air conditioner should be turned off.
What's more, seven bad habits make you feel sleepy in spring. Let's take a look at what they are
1. Not enough water. Even mild dehydration (a lack of 2% of normal body fluid) can affect energy levels. Dehydration makes the blood thicker, reducing the heart's ability to deliver oxygen and nutrients to various tissues and organs.
2. The intake of iron was insufficient. Iron deficiency affects the flow of oxygen to muscles and cells, leading to dullness, irritability, weakness and inability to concentrate.
3. Breakfast is not healthy. Good breakfast can stimulate metabolism and make people have enough energy throughout the day, but not having breakfast will make people feel lazy.
4. I love junk food. This can cause blood sugar levels to plummet, leading to fatigue.
5. Drink before going to bed. Alcohol can reduce blood sugar, inhibit the central nervous system, produce sedative effect, and eventually disturb sleep. This is because alcohol in the metabolic process will cause adrenal gland secretion disorder, so that drinkers easily wake up at night.
6. Playing with cell phones in bed. The blue light emitted by the display screen of tablet computers and smart phones will inhibit the secretion of melatonin, disturb the natural physiological rhythm of the human body and cause fatigue.
7. Staying up late and sleeping in. This can make it difficult to fall asleep at night and get up in the morning. You should also get up at a fixed time on weekends. If you want to take a nap, do not spend more than half an hour, or you will be more tired after waking up.
